* Machine-independent I/O routines for 8-, 16-, 24-, and 32-bit integers.
|
||
|
*
|
||
|
* Motorola processors (Macintosh, Sun, Sparc, MIPS, etc)
|
||
|
* pack bytes from high to low (they are big-endian).
|
||
|
* Use the HighLow routines to match the native format
|
||
|
* of these machines.
|
||
|
*
|
||
|
* Intel-like machines (PCs, Sequent)
|
||
|
* pack bytes from low to high (the are little-endian).
|
||
|
* Use the LowHigh routines to match the native format
|
||
|
* of these machines.
|
||
|
*
|
||
|
* These routines have been tested on the following machines:
|
||
|
* Apple Macintosh, MPW 3.1 C compiler
|
||
|
* Apple Macintosh, THINK C compiler
|
||
|
* Silicon Graphics IRIS, MIPS compiler
|
||
|
* Cray X/MP and Y/MP
|
||
|
* Digital Equipment VAX
|
||
|
*
|
||
|
*
|
||
|
* Implemented by Malcolm Slaney and Ken Turkowski.
|
||
|
*
|
||
|
* Malcolm Slaney contributions during 1988-1990 include big- and little-
|
||
|
* endian file I/O, conversion to and from Motorola's extended 80-bit
|
||
|
* floating-point format, and conversions to and from IEEE single-
|
||
|
* precision floating-point format.
|
||
|
*
|
||
|
* In 1991, Ken Turkowski implemented the conversions to and from
|
||
|
* IEEE double-precision format, added more precision to the extended
|
||
|
* conversions, and accommodated conversions involving +/- infinity,
|
||
|
* NaN's, and denormalized numbers.
